This invention relates to a carbonpaper folder adapted to contain a multiplicity ofsheets of carbon paper and to be packed in a conventional cardboard box along with a number of other similar folders packed with carbon, paper, and has for its purpose to afiord a folder consisting of afolded single sheet'of cardboard or heavy paper which completely covers and protects the sheets of carbon paper whenclosed and includes a cover portion that when unfolded or opened receives the carbon and record or copy sheets in alternate arrangement for manifolding' and locates them for; assembling in proper relationship so that the stack of carbon sheets and record sheets can be easily removed for plac'ementin a typewriter. v V

More particularly the invention has for its object to afford a one-piece folder so constructed that when-in folded relation, the carbon sheets are maintained between two flat parallel areas of thefolder and when unfolded; the supporting portion and cover portion are separated by a carbon-sheet elevating portion that raises the carbon sheets at one end for conveniently removing them, while the opposite end of the cover portion is provided with a flap that when folded.

canassume a perpendicular position and enables readily positioning th record'and carbonsheets in alined. relationship. H

A furtherpurpose of the invention is to afiord a carbonpaper folder consistingof a single sheet of paper or cardboarcloperable in the manner described a bove,-which can be manufactured at a minimurn cost and packed in a conventional carbon paper-boxso that the individual folders can be removed and used by operators at difierentlocations, each operatorjbeing enabled by the construction of the folder to readily position and assemble a series of carbon sheets {and record sheets on the folder for manifoldihg;

- To these and other ends; theinvention consists in the construction and arrangement of parts that {wt-u appear clearly from the following de-'' scription when read m conlunction' with the accompanying drawings, the novel features b'ein'g cation.-

In the drawings:

' "ig; 1' is. a plan view'of afol'der constructed in accordancewiththe invention; showing the cover portion in folded relationship over the supporting portion and a'multiplicity of carbon sheets,

the uppermost carbon 'sheet'j appearing, partially in dotted lines v Fig. 2 is a rear elevation of the same;

pointed out in the claims following the s'pecifif Fig. 3 is a view in side elevation showing the position of the supporting and cover portions when unfolded for assembling record and carbon sheets, with some carbon paper sheets restin on the supporting portion elevated at one end, and a multiplicity of alternating record and carbon sheets arranged on the cover portion ready to be removed;

Fig. 4 is a perspective view showing the posi'- tion of the parts when unfolded With carbon sheets on the supportingportion elevated at one end, and showing in dotted lines in position occupied by a record sheet when positioned on the cover portion, and

Fig. 5 is a plan view illustrative of a record sheet superposed on a carbonpaper sheet, in

their relative positions for manifold assembly. The invention of this application is an improvement on the structure of Patent No. 2,361,698, October 31, 1944, which is restricted in its use to the beam which the carbon paper folders are packed. With applicants structure, any number of carbon paper folders can be packed in a conventional cardboardcarbon paper box, and each folder when removed from the box can be used in the'desir'ed manner to permit read assembly offcarbon and record sheets on the folder itself .for'mani'folding. This permits distributing folders tooperators at different 10- cations and each operatorfwith her folder can assemble carbon sheets and record sheets easily and in the shortest time. The prior patented structure requires a' specially constructed box that is considerably more costly to manufacture than the conventional carbon paper box and the carbon sheets are packed in conventional plain folders. With such arrangement, the carbon and recordsheets can be assembled formanifoldin only in the box containing the folders, and, eaclioperato'r must have a box to perform the, manifold assembling operation, thus making it impossible to distribute folders and permit each operator toassemble carbon and. record sheets for manifolding with "hero folder. Applicants" structure, enables each folder to beusedindependentl-y of thebox to effect manifold asserm. blingin the desired: fashion, and, employs a much more economically constructed box. I

Referring :more particularly to the drawings in which like reference numerals refer to the same parts throughout the S vern viewsjthe folder consists of an; integral orpne-piece sheetpf heavy paper or light cardboard including a carbon-papersupporting portion 1 and, a cover portion 2 while ,3 designates an elevating portion 3 connected to the supporting portion l by a fold or crease 4 and to the cover portion 2 by a fold or crease 5.

Referring to Fig. 4, the folds or creases d and 5 respectively are such that the elevating portion 3 bends downwardly away from the supporting portion I and bends upwardly away from the cover portion 2 when the parts are unfolded, and when folded, the elevating or connecting portion 3 assumes a horizontal position in alinement with the supporting portion I, as indicated in Fig. 2, and the cover portion 2 folds over on the connecting portion 3 and supporting portion I along the crease or fold 5, as indicated in Fig. 1.

The supporting portion I is provided with a flap 6 foldable along the line I from the horizontal position shown in Fig. 1 where it overlies the end of the cover portion to the vertical, position illustrated in Fig. 3, while 8 designates a flap connected to the cover portion 2 and fold able along the crease or fold 9 from the horizontal position beneath the flap 6, as shown in Fig. l, to the perpendicular position as illustrated in Fig. 4.

The structure of the folder and the relation of the creases or folds 4, 5, l and 9 are such that when the parts are unfolded as in Fig. 4, the flaps or walls 6 and 8 and the elevating portion 3 automatically assume the perpendicular positions illustrated in Figs. 3 and 4, and when the cover portion 2 is folded over on the supporting portion l to cover and protect the carbon sheets, the elevating or connecting portion 3 assumes a horizontal position in continuation of the supporting portion I and underlying the cover portion 2 folded thereon, see Fig. 2, the flap' or Wall 3 likewise assuming a horizontal position beneath the flap or wall 6 that folds thereover, and the folder when in this position encloses a multiplicity of sheets of carbon paper and is positionable in any conventional box.

Several such folders, each containing a number of carbon paper sheets, can be packed in a conventional cardboard box and removed individually foruse at different locations, permitting each operator to conveniently arrange a series of record or copy sheets and carbon paper sheets for. manifolding by opening the folder so that the parts assume the positions illustrated in Figs. 3 and 4. 'When in such position, a record or copy sheet H is first positioned on the cover portion 2 with one edge against the flap or wall 8. The uppermost carbon sheet is then removed from the pile of carbons and supporting portion 1 and positioned over the record sheet, with one edge against the positioning wall or flap 8. The topmost carbon sheet is readily engaged by the operator by reason of the raising of the carbon sheets at one end over the vertically disposed elevating portion 3, and any number of record'sheets and carbon sheets can be alternately arranged in this fashion until the desired number are positioned for the manifolding operation, being then removed by the operator who grips them as an entirety through the notch I2 at one edge of the cover portion 2.

The carbon sheets are somewhat longer than the record sheets, see'Figs. 3 and 5, affording a gripping portion 13 on the carbon sheet at one end and opposite corners of the carbon sheet are cut away as at M and I5, so that when the typing operation is completed, the carbon sheets are easily separated in a group from the record sheets by holding the record sheets at one corner adjacent to the cut-away portions [5 of the carbon sheets, and gripping the carbon sheets by the extended gripping portions [3. When the carbon sheets are thus removed, they are repositioned on the supporting portion 1 for further use when needed. With this method of operation, the carbon sheets when repositioned on the supporting portion after use are inthe reverse order from their original position so that in successive typing operations, different portions of the carbon sheets are subjected to wear, and thus there is assured a more even distribution of work on the carbon sheets and their operative life in this fashion is considerably increased, while still permitting the use of paper folders packed in a conventional cardboard box.

While the invention has been described with reference to the particular structure herein shown, it is not limited to the details disclosed, and this application is intended to cover such modifications and departures as may come within the purposes of the improvement and the scope ofthe following claims.
